Constraints on Dynamical Dark Energy Models from the Abundance of Massive Galaxies at High Redshifts
N. Menci, A. Grazian, M. Castellano +9
We compare the maximal abundance of massive systems predicted in different dynamical dark energy (DDE) models at high redshifts z = 4-7 with the measured abundance of the most mass…

A Stringent Limit on the Warm Dark Matter Particle Masses from the Abundance of z=6 Galaxies in the Hubble Frontier Fields
N. Menci, A. Grazian, M. Castellano +1
We show that the recently measured UV luminosity functions of ultra-faint lensed galaxies at z= 6 in the Hubble Frontier Fields provide an unprecedented probe for the mass m_X of t…
